To aZZwhom it may con-cem: i

YBe itknown that I, AlHoMAs H. PITHER,

. citizen of the United States residing at Chicago," in the county ofCook and State of Illinois, have invented a certain new and usefulImprovement in Ceiling-Fan Motors, of which the following is a full,clear, concise, and exact description..- l

My invention relates `to motor driven mechanism of the type wherein thedriven 'member surroundsthe driving member kand is rotated thereby; lThe vobj ect of my invention is to provide a simple and compactstructure, maximum efficiency, with a minimum of My invention provides astructure wherein a highspeed motor ma be used and any desire variationof speer of the driven member obtained without com' licated gearing andlpa'rrangemefnts` My invention consists of a rotatable membersurrounding a motor and c lriven'tliereby, the driving element of themotor being movably adjustable with relation to the rotatably- /tljiegearing engagement therewith and thereby to control the speed at which.the rotatable `niemberis driven. i f f 'In the preferred embodiment ofmy invenpivoted in a Jframe to swing on a horizontal axis and the drivenmember Acomprises a casing rotatably mounted on the vframe and having anannular portion in en` gaveme'nt witha driving gear carried on the en ofthe motor shaft.

The engagement of the gear with the annular ing is thus renderedadjustable byswinging the motor' on its pivots. Y A further feature ofmy invention consists inthe means ofmountingtlie casing` on thesupporting frame or bracket, the bearing for -A the rotatable casingcomprising an oil-cu mounted upon 'the supporting frame.

IAnother feature of my invention consists in the 'p articular means.employed for swinging the motor on its pivots, said means comprisiiig alink and ratchet mechanism by.

means of which the motor may be adjusted and held in its adjustedposition.

In the accompanying drawings I have shown myirivention embodied in aceiling fan.

having a Patented Dec. 24, 1907 I be readily understood by reference to`said I drawings, in which Figure lisa side elevation of a ceilin fan;Fig. 2 is aside elevation-showing, by lfu and dotted lines respectivelyJtwo positions of the adjustable elements, the casing being shown insection; Fie'. but taken at right angles thereto; Fig. 4 is a.fragmentary detail sectional 'view' of the link -an ratchet mechanismfor adjusting the mopr; and Fig. 5 is a section on'the line 5-5 of Jikeparts are desi nated by similar characters o f reference t roughout theseveral views. f`

The electric motor M is mounted on horizontal ivots 1, 1, upondiametrically opposite, si( es of a ring-like frame or bracket 2, whichis suspended in the usual manner u 'on the lower end of a standard orhanger 3.

The le` ver 5 cariies a pawlcomprising a pin 11', slidable longitudinally of the lever and having aspring-thrust engagement .to hold it in its adjusted" position betweenthe teeth 10. By operating tlie handle 9, therefore, the toggle levermay be operated to swing the motor to any desired position and the-partswill be heldin their adjusted positions.

in the position of the parts shown in full lines in F '2, the center ofthe disk 14 is in engagement with the rim 13 in which position themotor. receives no current, sinee, es shown in Fig. 4, the switchingmechanism 15 is in its open position. nnism is preferably of the type ofsnepswiteh shown in United States Letters Pntent No. 82h52?, te Herold1t. Nellnmin issued Mey Sth, 1906, sind hence needs no detailedydescription. l adept seid snapswitcli for use in connection with in vinvention by providing the link 16 thereof with n. biiurrntedend, orwith prongs 1?,.171. in the normnl or inoperative position of the inn, elug 1b upon.,the link 4 lies between seid prongs.V In moving' the handle9 one iioteh or to the 'lirst operative position, seid lug engages withthe prong 17, moving` said prong` out of tno pero -oi sind lug, :indthrowing the switeh 15 into its closed position. At the seine time, sindmovement of the link 1G on its )ivot throws the iron" 17 in io'sition tobe engaged ,by the lug lin its return inove-v ment,` and henne in movingthe handle 9 to its initiel position from its iii-st or slowest' speedposition the switch ilis thrown: open and the parts restored to thepositions shown'` in Fig., 5. By this simple arrangement, the firstmovement of the operating liendle in one direction elosesthe switch, endthe last movement in the reverse direction opensthe seme.'

As shown most clearly in Fig. 2, the movenient oi the handle 9 operatesthe toggle iinks and swings the motor on ,its horizontal pivotal exis,thus ehn-ligging 'the radial enffegement of the disks 14 vwith theannular {iii-nge or riin 13.
